To all wit/on it may amt/cm:

Be it known that I, \Vnmun iLBeuxauo, a citizen of the United States, residing in New Haven, county oi New llaven, and

State of Connerticut have invented certain new and useful Improvementsinlliers or, Similar Tools, of which .the following}, is a full. clear, and exact description.

This invention relates to an improved 1) tool ot' the plicr, or lover handle, type, which My invention, provides a tool which is especially well adapted for ,use in c nne ting theerosschains, or tread chains, with the side chains, and disconnecting; them titer-e from. 'lhejmproved tool is adapted to operate in a simple and elleetivemanner on the wella known double books by which the tread chains are connectedwith the side ,chains,

either for securing said, hooks to the side chains, or (liseoimeeting,them therefrom.

As a result, the tool is admirably, ada 'ited for use by automobilists, fOliflll provides a,

very handy and convenient means for mak-, 111g repair-son the roach-tor elsewhere, when 9 one or more of the tread chains are worn through, or become nseless fromsome other cause.

My ii'nproved tool is also provided with a novel form of end cutter which may be used for severing the links of the sidevchains, and

for various other purposes.

Anothe' advantage of my invention res sides in the tact that the improvements are applieableto a simple form ot', compound tool for the use of autom bilist-s,,in which,

a number of valuable features aieeoinbincd.

To these and ,otherends, the invention consists in the novel features and combinations of parts to be hereinafter described 4- and elai med.

. Referring to the drawings, 20 and 21 indicate vthelevcr handles of the tool, which handles are preferably eonstructmllot sheet metal bent to present a U-shaped or channeled cross-section. The forward end of the member 20 is cut away at 22 to accommodate the shanks of subsidiary jaws 23 and 24, but the forward. extremity of said member 90 is formed to present a main jaw 2:3 of U- shaped cross-section consisting, of an inner serrated wall 26 and parallel side walls '27. The forward endof the member 21 is constructed similarly, it being cut away at 28 and having, at its. forward extremity a jaw i2), consisting of .a serrated inner wall 30, and parallel sidewalls 3L. The open part of the member 21 at the rear of the jaw 29 is bent outward at so as to straddle the open portion of the member '20, and the members are pivoted together by meansot a pivot pin Ill) passing through the. open ,forked portions 011 both meu'ihors.

lt willbe understood from the foregoing description that both of the jaws 2n and Q!) are of U-shapcd (amiss-section: This shown partioularly;in Fig. The inner walls 26 and 30 ot' the respective jaws lie parallel to each other and the respective pairs of side walls 27 and 31 extend outward from the inner walls in opposite directions. The inner walls so and 130 are prc'ferably providedwith transverse serrations Q69, 30?, and the walls '26 and 30 are pref erably curved in the manner shown in Figs.

1 and 2,,soas to provide surfaces which may be. used for {gripping in a very effective manner round or polygonal bodies of various sizes as the jaws Q5 and 29 are opened to a ,greater or less extent.

The subsidiary jaws 23 and 24 hereinbefore mentioned are mounted to operate in the space between the side walls 31. of the jaw .39, and in the space'hetween the side walls 2711f the jaw 25,- I place an instru- ,..n1entality, siich as a hammer head, 34-. This hammer head is rigidly secured to the jaw 25 by means of a rivet 35 passing through the side walls 27, and through a hole in. the shank of the hammer head. The connection is madev rigid and strong by upsetting the rods of the rivet 35, as shown in Fig. 5.

Referring now to the detailed construclion ol the subsidiaiw jaws 3-1; and 21-, it will be noted that the jaw 21 comprises a shank iZ-tt, lying substantially at right angles to the main part oi the jaw and extending lengthwise of the main jaw 29 between the side walls 31. The shank 3t; is about half as wide as the space between the inner surfaces of the walls 31. The jaw 23 has a generally similar shank 3T fitted between the walls 31 alongside the shank 36, as shown in Fig. 5. The shank 36 of jaw 2t is fixedly pivoted to the forward extremity of the jaw 29, in advance of the main pivot 33, by means of a pivot pin 38 extending through a circular hole in the shank 36 and corresponding cir cular holes in the side walls 31. At the 0pposite end of the shank 36, 2'. 6., at the rear of the main pivot said shank has a sliding connection with the member 21. This connection is etl'ected by means of a pin 39 connecting the side plates of the member 21 and engaged by a slot 36 extending lengthwise of the shank 3G. The shank 37 of the jaw 23. on the other hand, is slidable on the pin 38 by means of a slot 37 and fixedly pivoted on the pin 35). By this mounting, he jaws 523 and 2 1- will be separated from each other as the handle members and 21 are separated, whereas said jaws 23 and. 2 1 will be approached toward each other as the handle members 20 and 21 are brought together, substantially as described in my application Serial No. 732,550, filed November 20, 1912.

In order to carry out the functions hereinafter described, the working portions of the jaws .23 and 2% are formed as follows: Each jaw is provided at some distance inward from its outer end 40 with a cutting edge 41 directed transversely thereof across the full width of the jaw. At one side of the edge 4-1, the jaw is concaved, as shown at 42, and at the opposite side of the edge, 4-1, seats 43 and 44 are provided extending" parallel with each other across the full width of the jaw. and in parallelism with the cutting edge 41. The edee 1-1 is at the apex of a wedge-shaped projection 41, one side of which is defined by the concave surface 42, while the opposite side is constituted by a portion of the concave surface of the seat 13. The transverse seats 43 and 4-1- are of approxlmately semi-circular crosssection and are separated from each other by a ridge 4-5. lll'oreover, these seats are provided with serrations or ribs, extending transversely thereof, 2'. 6., longitudinally of the jaw, so that chain links, and. the like,

l l r l may be firmly gripped between the opposing jaws. When the cutting edges 41 of the respective aws are in contact, as shown in Fig.

l, the bottoms of the seats 13 and 4- 1 of one jaw will preferably be spaced from the corresponding seats ol. the other jaw to about the extent indicated in Fig. l. The cooperatinn concavitics t2 and -13 of each of the jaws E23, 2-! create in conjunction a marginal wedge-shaped member all between them, which member extends transversely of the jaw and is adapted to act as a cutter, or as a separating device, as hereinafter set forth. Simihirly, the cooperating coin-avities 13 and 4-1 of each jaw also create between them a marginal wedge-shaped member to adapted to act as a spacing element, as hereinafter set forth.

Supposing that a tread chain of the wellknown form is to be connected to a side chain, the procedure is as follows: A U- shaped double hook 4-6 of commercial form (Fig. 14) is run through one of the end links of the tread chain. The legs or branches t? of the double hook member are then squeezed together in the manner shown in Figs. 7 and 15, so as to connect the member 46 securely to the tread chain, and bring together the books 48 of the member it so that said books may be readily attached to the side chain. In bending together the legs or branches 47, the hook member is placed between the jaws 23 and 24 in the manner shown in Fig. 6. In the case illustrated, the lens or branches 4'? are disposed lengthwise oi the opposite seats 43, so that when the jaws 23 and 2st are brought together, the member 46 will be bent in the form shown in Fig. 7. The next step, via, connecting the hook member at? with the side chain, is carried out in the manner shown in Figs. 8, 9 and 10. The hook portions 48. which are then in close contiguity with each other, are passed through one or more links of the side chain, and the member 46 is then placed between the jaws 23 and 24 in the manner shown in Figs. 8 and 9. One of the hooks 4-8 rests in one of the seats 1 3, and the other member 48 rests in the adjacent seatti. Similarly. one of the legs 47 of the hook member lies in the other seat 13, and the other leg of the hook member lies in the other seat 44-. The jaws Q 3 and Qt are then approached toward each other, so as to bend down both books 4.8 in the form shown in Figs. 10 and 16, under which conditions, the hook will be securely iast'mied to the side chain. Supposing: that one of the tread chains is broken, said chain may be easily disconnected from the side chain for making i repairs, by 118111;: the improved tool in the manner shown in Figs. 11 and 12. The wedges 41 of the opposing jaws 23 and 241- are brought together between the ends of the hooks 48 and the main body of the hook member 46. The jaws 23 and 2 are then ap proached toward each other, as shown in Fig. 12, and the ends of the hook member will be forced outward to release the side chain. The concave portion 42 of each jaw, which forms one side of the separating, wedge, permits the wedge to be easily in sertcd between the corresponding tip or extremity of the hook member and the body portion thereof, owing to the fact that said concave portion conforms to a certain extent to the cross-scctimial curvature of the body portion. ()n the other hand, the curvature of the seat 421), which detines the other side of the wedge, conforms approximately to the cross-sectional curvature of the tip or extremity l8. By this construction, the separating wedges may be introduced into the hook portion of the member 46 to a consid crable extent before the jaws are subjected to pressure.

Fig. 13 shows the manner in which the cooperating edges 4.1 of the jaws 23 aml 24 may be used for cutting. These edges 41 constitute an end cutter which is useful for cutting chain links, and for various other purposes.

The compound tool shown in the drawings has been found of special advantage to automobilists. The jaws 23 and .24 have the numerous functions hereinbefore noted in connection with the adjustment and repair of tire chains, and the main jaws 25 and 25) may be used to remove nuts, and to perform various other otlices, acting either as a wrench or a vise. The hammer 3%, associated with the jaw 25, increases still :further the utility and scope of the tool. Of course, I have not attempted to illustrate and describe the various modifications of the construction which may be adopted within the scope of my invention, as expressed in the claims.

What I claim is l. Pliers or a similar tool having each of its jaws provided with a transverse wedgeshaped member at the end of the jaw, one side l'ace of said wedge-shaped member bein; constituted by a concave portion on the outside of the jaw extending to the forward extremity of the latter, and the other side ot said wedge-shaped member being constitutcd by a portion of the wall of a transverse seat. in the jaw; substantially as de scribed.

2. illiers or a similar tool having each of its jaws provided with a transverse wedgeshaped member at the end of the jaw, one side face of said wedgoshaptal member being constituted by a concave portion on the outside of the jaw extending to the forward extremity of the latter, and the other side of said wedge-shaped member being constituted by a portion of the wall of a transverse seat in the jaw, said wedgeshaped members of the respective jaws bein; adapted to meet each other as the jaws are brought together; substantially as described.
